## Limitations

* Today Azure Synapse Link for Azure Cosmos DB is supported for SQL API and Azure Cosmos DB API for MongoDB. It is not supported for Gremlin API and Table API. Support for Cassandra API is in private preview, for more information please contact the [Azure Synapse Link team](mailto:[email protected]).
* Azure Synapse Link for Azure Cosmos DB is supported for SQL API and Azure Cosmos DB API for MongoDB. It is not supported for Gremlin API, Cassandra API, and Table API.

* Currently, the analytical store can only be enabled for new containers. To use analytical store for existing containers, migrate data from your existing containers to new containers using [Azure Cosmos DB migration tools](cosmosdb-migrationchoices.md). You can enable Synapse Link on new and existing Azure Cosmos DB accounts.
* Analytical store can only be enabled for new containers. To use analytical store for existing containers, migrate data from your existing containers to new containers using [Azure Cosmos DB migration tools](cosmosdb-migrationchoices.md). You can enable Synapse Link on new and existing Azure Cosmos DB accounts.

* For the containers with analytical store turned on, automatic backup and restore of your data in the analytical store is not supported at this time. When Synapse Link is enabled on a database account, Azure Cosmos DB will continue to automatically [take backups](./online-backup-and-restore.md) of your data in the transactional store (only) of containers at scheduled backup interval, as always. It is important to note that when a container with analytical store turned on is restored to a new account, the container will be restored with only transactional store and no analytical store enabled.

* Accessing the Azure Cosmos DB analytics store with Synapse SQL provisioned is currently not available.

* Network isolation for Azure Cosmso DB analytical store, using managed private endpoints in Azure Synapse Analytics, is currently not supported.
